a customer brought in a iphone 7 plus for a screen repair, but it had a broken lcd so i was unable to test it before i opened it. (note ive fixed about 30 7/7plus without issues.) anyway after installing the new screen I found the phone lagging and freezing up. but it wasnt my screen because the power button was also lagging and when i opened voice memos the record icon was unable to be pressed, also i only use oem apple lcd replacement parts, refurbished by myself so i know they arent fake. anyway I tried to restore the phone to see if that would fix it because i know there have been alot of issues with ios11 and im getting error -1 and now the phone is stuck in recovery mode…if tried updating/and restoring in dfu still not working. another note i tried both itunes and 3utools. when i flash on 3u i can see that it fails at 80% when trying to flash fuddata.
Change IC u3601 and flash firmware again
This is a pretty old error code. Try this https://m.youtube.com/watch?v=8OYjEP8xtB…
This is the classic error code for baseband issue now recalled by Apple on iphone 7 Model A1660 only. You need to take it to a real Apple store and they will send to Apple to determine replacement eligibility. https://www.apple.com/support/iphone-7-n…
iPhone error 1? Joyoshare Ultfix can help you repair it without data loss. I used it to do the same.
